Subtotal: $17.95
BIG MAMA GRO-BLOCK™ is the largest block ever produced by Grodan. It is 8″ x 8″ x 8″ and contains over twice the amount of Rockwool as the popular HUGO GRO-BLOCK™.
When your plant outgrows its current block, just place it on top of BIG MAMA.
BIG MAMA is solid wool and does not have a precut hole thus it is suitable to hold any smaller-sized block on top (even a HUGO).
__________
Grodan Rockwool is an excellent quality stonewool substrate with a very high water holding capacity. Rockwool is absolutely free of disease, salts, and weed seeds. It has no Cation Exchange Capacity (CEC) so growers can take advantage of a nutritional program specifically tailored to their choice of crop. Set your plants into the Rockwool blocks then place those on top of the slabs. The roots will grow through the block and the slabs.
Nutrient solution may be applied through a spray or drip-emitter either directly to the slab or through the growing blocks. Blocks are commonly used for germination of seed and rooting cuttings. The vertically-oriented fibers in the blocks promote good downward root growth.
